Q

Explain the continuous tones:

A

Two continuous tones can be heard:
– a 310 Hz tone when Nr is below 360 rpm
– a 285 Hz tone when max. takeoff rating is exceeded
— After 1.5 sec. delay if power remains within transient range
— Immediately when max. transient rating is or will be exceeded during fast power increase

  1. Collective pitch - REDUCE to maintain Nr in normal operating range or power within limits.
  2. Engine parameters - CHECK

Q

What is the autorotation procedure over land after an engine flame-out?

A
  1. Collective pitch - REDUCE to maintain Nr in normal operating range
  2. IAS - SET to 65 kts
    - If relighting impossible or after loss of tail rotor thrust
  3. FFCL - OFF detent
    Time, height and circumstances permitting:
    - Fuel shutoff cock - OFF
    - FUEL PUMPs - OFF
    - BATT - EMER SHED
  4. Maneuver the aircraft into wind on final approach
    - At height + 70 ft
  5. Cyclic stick - FLARE
    - At 20/25 and at constant attitude
  6. Collective pitch - GRADUALLY INCREASE to reduce the rate of descent and forward speed
  7. Cyclic - FORWARD to adopt a slightly nose-up landing attitude (<10degrees)
  8. Pedals - ADJUST to cancel any side slip tendency
  9. Collective pitch - INCREASE to cushion touch-down
    - After touch-down
  10. Cyclic, collective, pedals - ADJUST to control ground run
    - Once the a/c has stopped
  11. Collective pitch - FULL LOW PITCH
  12. Rotor brake - APPLY below 170 rpm

Q

Explain the autorotation procedure over water:

A

Apply the same procedure as over land, except items 10, 11, and 12, but maneuver to head a/c equally between the wind and wave direction on final approach. Ditch with minimum forward speed (IAS < 30 kts) and rate of descent. Then apply:
10. Collective pitch - MAINTAIN
11. Doors jettison handles - PULL-UP
12. Rotor brake - APPLY
Abandon a/c once rotor has stopped

Q

What is the procedure for a complete loss of tail rotor thrust in cruise flight?

A
  • Approach and landing
    1. Carry out an autorotative landing according to the autorotation procedure
    2. During descent FFCL - REDUCE

Q

What are the symptoms of a loss of tail rotor control?

A

Jamming of pedals or pedals effectiveness loss. These conditions induce an inability to change the tail rotor thrust with the pedals

When airspeed is less than 20 kts and particularly near to the ground, go-around may be impossible due to the loss of the vertical fin efficiency

Q

What is the procedure for a loss of tail rotor control?

A
  1. Cyclic and collective - ADJUST to set IAS to 70 kts in level flight
  2. ACCU TST - PRESS, tail rotor load compensator depressurizes
    - After 5 sec:
  3. ACCU TST - RESET to OFF position
  • Make a shallow approach with a slight left sideslip. Perform a running landing. The sideslip will be reduced progressively as airspeed is reduced and collective is applied to cushion the landing
  • Landing is made easier with a RH wind component

Q

What is the procedure for failure of both VEMD screens?

To avoid any power overlimit, the max. authorized power will be the power needed to establish level flight with the following law:
IAS kts = 100 kts - 2 kts/1000 ft

Q

How are caution messages displayed on the VEMD?

A
  • When a parameter is off line, the parameter value is not displayed on the upper VEMD screen and the parameter scale symbology is displayed in yellow
  • Caution messages are self explanatory and the pilot shall comply with the action requested. If no light is lit on the CWP, no other action is required from the pilot
  • If an overlimit is displayed it is recorded in the VEMD and will be displayed on the engine page until Ng = 40% during the following engine start
  • If no light is displayed:
    CONTINUE FLIGHT
